Platform Womens Shoe

It has a platform and heal over 3 1 / 2 inches high, and have drawstrings. It seems to be about 40 era. I've been trying to research the same year and could not find one like him. Does anyone know of a website that could put the style number and determine the manufacturer and the year? You can still make out style number inside. Thanks in advance!

I'm pretty good at identifying vintage clothing and antiques. I can send a photo if you wish.
